Master with Confidence, Focus on Creativity
ISL, the transparent look-ahead limiter, lets you concentrate on your audio production while it ensures compliance with True Peak standards. No more worrying about sample-peak limits or headroom adjustments – just set your True Peak level and let ISL handle the rest.
Built for Professionals
- Standards Compliant: Adheres to ITU-R B.S. 1770 and related standards (including Apple “afclip”) for mastering, post-production, and broadcast.
- Prevents Distortion: Safeguards audio from quality loss during codec conversion (MP3, AAC) for flawless delivery.
- Surround Sound Ready: Supports surround formats up to 7.1.2 (ISL 2) for versatile post and film production.
- Advanced Processing: Unlike traditional limiters, ISL offers:
- Automatic TPlim control for subtle brick-wall limiting.
- Auto-release that adapts to low frequencies, maintaining transparency even in demanding situations.
- Intelligent processing that analyzes incoming audio and adjusts for low-frequency content, further enhancing clarity.
Visualize Your Limiting
ISL’s innovative steering and ducking meters provide clear feedback, allowing you to achieve your desired results with ease.
Streamlined Workflows

- Post & Broadcast: Achieve broadcast-quality limiting with seamless True Peak compliance (ITU-R B.S. 1770-4 compliant). Focus on production while ISL handles compliance transparently.
Industry Recognition: ISL’s inclusion in the Netflix Production Technology Alliance audio tool category highlights its commitment to meeting professional standards.
